<P>PROBLEM TO BE SOLVED: To surely prevent oil leakage by enhancing a sealing property of a hydraulic pump. <P>SOLUTION: In the hydraulic pump, a seal member 12 is arranged to an outer periphery of a pump driving shaft 11, and an oil reservoir 14 for reserving the leaked oil therein is provided in an inner periphery of an end cover 13 of a pump case in a position nearer to an atmospheric side than the seal member 12. An oil thrower 15 projecting in a collar shape over an entire periphery is arranged on an outer periphery of the pump driving shaft 11, and the oil which is to move outside through the pump driving shaft 11 is shut off by the oil thrower 15, and falls into the oil reservoir 14. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
